Fourteen years later, they sit in a mostly empty ­Hangar 17 at JFK Airport — the last remains of 9/11.

After the Sept. 11 attacks, the Port Authority stashed about 1 percent of the relics recovered from the World Trade Center ruins, everything from crushed police cars to store mannequins.

All but 226 of the 2,563 pieces have been distributed— sent to 1,472 organizations in the United States and abroad.

Now the PA plans to dole out the rest by March, when it will demolish the hangar.

J.C. RiceOf the leftovers, 65 already are spoken for. Recipients must agree to one condition: They must display the items publicly.

J.C. RiceInspired by one of its students who visited the 9/11 Memorial with her family, Cracker Trail Elementary in Sebring, Fla., will get a Marvin the Martian Spaceship Alarm Clock that was on sale in the WTC concourse and a tattered Bankers Trust notebook.

The school requested a relic after Ellie Brinling, 8, brought five seeds from The Survivor Tree at Ground Zero and cultivated one to plant on campus.

Ellie is excited that the PA has granted her wish.

“It will help the kids understand how important it was on that day and how sad it was,” Ellie told The Post.

This week, the Trolley Museum of New York in upstate Kingston will get PATH Train Car No. 143, found virtually unscathed amid the ruins. The museum plans to build a 9/11 wing to house the car.

“My vision is to have people walk through it and around it so they can get a feeling of reverence for the people who died that day,” said Erik Garces, the ­museum’s president.

Fulton Montgomery College in upstate Johnstown was granted a 32-foot-tall, 36,000-pound section of the north-tower antenna, which it will erect on a platform. A Ground Zero worker taking classes there had asked for a WTC piece, said the school’s president, Dustin Swanger.

Elks Lodge 1493 in Beacon, Dutchess County, will get the last remaining steel beam, which bears holes left by Ground Zero workers who cut out crosses and Stars of David to take as souvenirs. It will go in the lodge’s front yard.

“Everybody was ecstatic to get a piece of the World Trade Center to never forget what took place,” said Carl Oken, a retired correction officer and chair of the lodge’s Americanism committee.

J.C. RiceStill available are large items such as a 30,000-pound piece of the underground parking structure, elevator motors and a 5 WTC sign.

Odd objects include Lens­Crafters optical tools, wigs, Casual Corner shirts, a costume-jewelry display and mannequins, including one in a red metallic bra and panties and another in a swimsuit labeled “Sentimental NY.”

“We hope they will all be taken, and if not, we will make decisions on how they can continue to be stored,” said PA spokesman Steve Coleman.

None of the PA items belonged to victims, officials said. The NYPD said it is holding 3,483 unclaimed personal effects, including 374 pieces of jewelry and other items such as glasses, wallets, keys and clothing.
